JavaScript代码（一）

1.将URL参数返回，并转化为对象的方法：

 function getUrlParams() {
        var url = location.search;
        var params = new Object();
        if (url.indexOf("?") != -1) {
          var str = url.substr(1);
          strs = str.split("&");
          for(var i = 0; i < strs.length; i ++) {
           params[strs[i].split("=")[0]]=strs[i].split("=")[1];
          }
        }
        return params;
    };

2.将数值转换为1,0标志位

function splitToArray(number){
    var targets=[];
    var remainder;
    var temp;
    for(i=number,j=1;number>=j;i=i-((i/j)%2)*j,j=j*2){        
        remainder=(i/j)%2;
        if(remainder==1){
            targets=targets.concat(j);
        }
    }
    return targets;
}

3.将1,0标志位转换为数值

function caculateByArray(targets){
    var target=parseInt(0);
    for(i=0;i<targets.length;i++){
        target=target+parseInt(targets[i]);        
    }
    return target;
}
